Application filed December 29, 1915. Serial No. 69,198.

To all whom it may concern .Be it known that I, SAMUEL GEISMAN, a citizen of the United States, and a resident of the city ofNew York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Method of Producing'an Impression-Plate, of which the following is a full, clear, and exact description.

This invention relates to a method of producing an impression plate and has for an object the provision of improved steps whereby an impression plate maybe produced quickly and at a small expense.

Another object in view is to provide improved steps in the process of producing impression plates whereby any desired' impression may be quickly and easily secured substantially w in the natural state on the impression plate and be, by proper steps, trans ferred to any suitable material, as for instance. leather, paper, cloth, etc.

In the accompanymg drawings: Figure 1 is a plan view with certain parts broken away disclosing a plate adapted to receive an impression. Fig. 2 is a section through Fig. 1 on line .Q -2. Fig. 3 is a top plan View of the plate shown in Fig. 1 with a piece oflace arranged thereon. Fig. 4 is a section through Fig. 3 on line 4-4. Fig. 5 is a plan View of a die or male plate embodying certain features of the invention. Fig. 6 is a section through Fig. 5'on line 6.-6. Fig. 7 is a top plan view of the die shown in Fig. 5 arranged on the structure shown in Fig. 3, part of the die being broken away. Fig. 8 is a section through Fig. 7 on line 7 7. Fig. 9 is a plan view ofthe impression plate after it has been plated with copper, part of the plate being broken away to show the copper die. Fig. 10isf. a section through Fig. 9 on line 10-10. `Fig. 11 is a plan view of a piece of leather or other material adapted to receive 12 is a section the final imprint. Fig. through Fig. 11 on line 12-12. Fig. 13 is a plan view of the die reproduced from the wax matrix as the same is applied to the article to receive the impression, part of the die being broken away. Fig. 14 is a section through Fig. 13 on line 14-14. Fig. 15 is a plan view of the nished piece of leather or other body which has received the impression on same, showing a reproduction of the lace disclosed in Fig. 3 and also the configuration'of the die shown in Fig. 5.

Y which may properly receive the impression and act as a primary or preliminary matrix .which may have a positive reproduced therefrom by electroplating.

After the wax surface has been prepared, as shown in Fig. 1, the piece of lace 4, or otherfmaterial having a design, is placed upon the plate. Preferably one repeat is placed upon the plate so the nal die produced may provide a number of repeats on a given surface and thereby producea umform arrangement ofan article of commerce.

However, as far .as the method is concerneda complete repeat or part of a repeat could l be arranged on the plate, or several repeats could be arranged on the plate. The lace 4 or other` member having the design thereon is merely smoothed out and laid loosely Aon the plate, after which the die 5 is placed on the lace, as shown in Fig. 7. The die 5 may contain any suitable raised portions 6, as shown-in Fig. 6, so as to represent diferent forms of expensive leather or other ornamentation as desired. The die preferably has a different design from the lace 4 and usually is a design of a more or less expensive vpiece of leather.

AfterI the parts have been arranged as shown 1n Figs. 7 and 8 the die is pressed tightly against the plate 1 so as to force the various raised portions 6 of the die into 100 the wax and in addition force the lace into the wax so that there will be a complete reproduction of the lace and the design on plate 5, as shown in the broken away part of Fig. 7. It -will be understood that some of the raised portions of the die will engage the closely arranged 'threads of the lace and be reproduced thereon, while other portions will engage the threads of the open-work portion of the lace, So that 'the reproduction of the threads appears as a part of' the reproduction of the said raised portions of the die, and still other portions will pass between the threads of the said open-work portion of the lace directly into the wax, so that only the design thereon will be reproduced. ln this way a Very complicated design may be cheaply and easily reproduced in wax. lf nothing else but the lace design was desired the die 5 could be made perfectly smooth 'and merely the lace forced into the wax.

`rAfter the parts have been pressed together, as shown in Figs9 and 10, die 5 is removed and the lace 4 is also removed, the

` ed with graphite or other suitable material and placed in a bath where it is electroplated, the plate being made sufficiently thick for producing a positive plate or die 9 which when used on the leather 7 (Fig. 11) Will produce a 'design 8 on the leather, as shown in Fig. 15, thus combining the design on the die 5 and the lace 4 in one article of commerce. The term leather has been used but it will be understood that any material or surface may be caused to receive the impression instead of the leather piece 7 without departing from the spirit of the invention.

llt will be seen that the steps of producing the final die 9 which is forced against the leather or article to1 be impressed includes the placing of the fabric of any kind between the die 5 and the plate 1. 'lhis fabric has been designated as lace, but it is of course understood that other fabrics may Lacasse be used, either textile, metal, or in fact any article which may be forced into the wan and the shape thereof reproduced. 'llhis step in producing the final wax impression saves or obviates the` necessity of cutting a die showing the configuration on the lace or anyother suitable object. In reproducing lace designs or designs of other kinds, as for instance, designs of leather, it is almost impossible to correctly Ireproduce the fine lines found in these designs, but by using the step of the process of interposing the article having the design thereon between die 5 and plate l the design may be reproduced quickly, easily and absolutely accurately.

`What l claim is:

The method herein described of producing an impression plate, consisting in placing on a plastic mass a sheet of tine openw'ork fabric having a design thereon, placing on the fabric sheet a die having a design thereon in the form of numerous raised portions, applying pressure to the die to force the fabric sheet and the projections of the die into the plastic mass, whereby a reproduction of the fabric and the design of the die will be produced in the plastic mass, removing the die and fabric sheet, and electroplating the surface of the plastic mass having the impression therein.
